Professor Murphy wants to set up a control chart to monitor the percentage of absenteeism in his introductory statistics course (50 students are registered). Absences per period for the last 15 class sessions are in the table below. Find the empirical control limits for a p-chart to be used in the future for monitoring class attendance (assuming that past experience is the appropriate attainable centerline for class absences).
$$\begin{array} { | l | c | c | c | c | c | c | c | c | c | c | c | c | c | c | c | }
\hline \text { Session } & 1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 & 11 & 12 & 13 & 14 & 15 \
\hline \text { Absent } & 5 & 0 & 2 & 2 & 3 & 8 & 10 & 3 & 5 & 5 & 1 & 2 & 0 & 2 & 3 \
\hline
\end{array}$$
